本文报道了一种简单的氮杂芳烃化合物二苯并[a，c]吩嗪(DPPZ)，它由同时荧光(S1→S0)和双室温磷光(RTP，T2→S0和T1→S0)组成，呈现单分子白光和三元发光。L国际委员会对DPPZ粉料的回旋坐标为(0.28，0.33)。据大家所知，这是第一个实现单分子白光发射的三元荧光和双RTP的案例。这一发现为进一步精确调制激发态实现低成本、稳定的三基色纯有机单分子白光发射提供了原型策略。
Herein, a simple aza‐aromatic compound dibenzo[a,c]phenazine (DPPZ), which exhibits single‐molecule white light with a ternary emission, consisting of simultaneous fluorescence (S1→S0) and dual room‐temperature phosphorescence (RTP, T2→S0and T1→S0) is reported. The Commission Internationale de l' Éclairage coordinates of DPPZ powder are (0.28, 0.33). To everyone's knowledge, this is the first case to achieve single‐molecule white emission with ternary emission of fluorescence and dual RTP. This finding provides a prototype strategy to realize low‐cost, stable pure organic single‐molecule white light emission with three standard primary colors through further precise modulation of excited states.
